FIELD OF THE INVENTION

The present invention generally relates to building systems, and is more particularly directed to a mobile service block system including prefabricated bathroom, kitchen and other service room units in a single compact and mobile form for installation and use in buildings.

BACKGROUND

In certain countries like Canada, each person consumes an average of nearly 329 liters of water per day. Energy and water conservation and management are becoming important concerns in building constructions. Also, saving space and minimizing the use of premium materials are also becoming important considerations when designing buildings.

Accordingly, there is a need for a building system and method that addresses at least one of the above-mentioned concerns.

Know to the Applicant is US patent application No. 2011/0209735 A1 made public on Sep. 1, 2011, in the name of ROWAN, and relating to a “shelter building”. This document describes a housing for emergencies or for those in need could be a short-term solution or may be set up as a longer-term shelter. The shelter may be flexible to grow and change enough to accommodate the individual, the family and the community. The shelter is more substantial than a tent and easier to assemble and transport as compared to conventional shelters. The shelter can be transported in a standard size truck bed (for example, 4 feet by 8 feet) and erected by two individuals in a minimal amount of time, typically less than an hour. The walls of the shelter may include various features, including shelving, bathing facilities, sinks, beds, lighting, and the like. The shelters may be designed to be connected to external electric and water supplies. Optionally, the shelters may be designed as stand-alone, “off-the-grid” units. The ceiling of the shelter may include one or more solar panels to provide power for the shelter. The shelter's container provides the essentials needed to sustain life. This takes away the need for standing in multiple lines and gives the much needed immediate help.

Despite this known technology, there is always a need to continue innovating and finding better and/or different ways of providing dwellings for people, in a quicker, easier, simpler, faster, more efficient, more economical, more reliable, more adjustable, more versatile, more adaptable, more environmentally-friendly, more sustainable and/or more desirable manner.

The kitchen unit 18 can also include a DEL lighting system 112. In the kitchen unit, storage areas 114 can be optimized for space usage.

In some implementations, the mobile service block system 10 is configured to receive energy and water efficient appliances 46 for use within the mobile service block system 10.

According to the present invention, as better shown in FIG. 5, there is also provided a method of installing a mobile service block system in a building comprising:

-   -   a) prefabricating a mobile service block system as defined in         any one of claims 1 to 5 and 7 to 12 at a manufacturing location         (step 200);     -   b) transporting the prefabricated mobile service block system         from the manufacturing location to a building location (step         300); and     -   c) connecting the prefabricated mobile service block system to a         plumbing and electrical infrastructure of the building (step         400).

Prefabrication Step

In all respects, prefabrication assists in installation at the worksite. First, this type of prefabrication construction encourages a better use of materials and generating much less losses. Skilled workers perform repetitive tasks and ensure a greater quality of assembly and in less time, thus resulting in cost savings. In the end, prefabrication offers better working conditions for workers and generates a minimal environmental impact.

In some implementations, the prefabricating step further comprises a step of storing a plurality of mobile service block systems at the manufacturing location, thus avoiding further transport.

Transporting Step

In some implementations, the prefabricated mobile service block system is wrapped in recycled cardboard during the transporting step. Such packaging minimally protects the contents until delivery. The distribution is done by truck, where the modules are stored and protected by reusable blankets in the semi-trailer box, until delivery at the building directly to the accommodation of the user. As shown in step 400 of FIG. 5, a “forklift” can be used to introduce the system on different floors and where the system is readily connectable for use.

In some implementations, the system consumes about 35% less water and 45% less energy than a similar standard residential development. Its durable design allows it to be moved from one dwelling to another and offers a long term solution. Obsolete components can be easily replaced, thus ensuring an extended life time.

Recycling Step

In some implementations, the method further includes a step of disassembling and recycling (step 500) the mobile service block system at an end of an operational life of the mobile service block system. Having reached the end of its useful life, the system can be largely disassembled and more than 90% recycled. After-sales service available on site can encourage users to send obsolete parts or the entire system to the appropriate recycling center.

According to the present invention, as better shown in FIGS. 4A and 4B, there is also provided a room unit 50 including a mobile service block system as defined above.

In some implementations, the mobile service block system 10 is displaceable between a daytime location for operational use during a daytime period (shown in FIG. 4A) and a nighttime location for operational use during a nighttime period (shown in FIG. 4B).

In some implementations, this prefabricated system can be pre-fitted with energy and water efficient appliances and can be characterized by various environmental aspects, including its FSC-certified wood structure (see step 100 in FIG. 5), low consumption of water and energy, durability, etc. Operation of the system is simple, flexible and easily adaptable to various buildings, as small as it is, provided that access to water and electricity connections is possible in the building.

Unlike prefabricated bathrooms and kitchens already available on the market, the system is distinguished by its mobility and overall ecodesign. Its size, its weight, small footprint, is easy to integrate a multitude of areas, as its low energy and water consumption and sleek design make it a great alternative.

By its small size, the system requires approximately 47% less raw materials when compared to several traditional kitchens, laundry room and bath designs. The construction of a frame and a trim structure of FSC-certified wood from a regional supply provides a guarantee of concern for resource management. The FSC label thus provides added value to the project. The choice of stainless steel also proves interesting because a large portion of the system comes from recycling local waste.

In some implementations, the system 10 is a 55 ft² mobile service block together with pre-fitted energy and water efficient kitchen, laundry and bathroom amenities. This prefabricated module and equipped with approved appliances is characterized by various environmental aspects, including its FSC-certified wood structure (see step 100 in FIG. 5), low consumption of water and energy, durability, etc. The operation is simple, flexible and easily adaptable to various facilities, as small as it is, if access to water and electricity connections are possible.

In some implementations, the design of the system is characterized by a comprehensive approach to product life cycle, from raw material extraction to disposal at end of life. Different economic, social and environmental issues were identified considering the stages of life cycle analysis and were addressed to propose a solution to the various problems of production and consumption that were observed. Various strategies were used to minimize adverse environmental and social impacts, including a selection of local materials that are durable and resistant over time. In addition, the small design of the module and its prefabrication ensures optimized production and improved resource management. The selected components of the module are there to reduce the consumption of water and energy.

In some implementations, the system on wheels fits various floor plans. Through its simple architecture, it gives way to an airy, free expression that everyone can customize. The system is ecologically designed and consumes resources responsibly. The durability of the module allows it to be moved. Thus, in the long term, it can easily be transported by truck, connected and reused in a new space, as if the system was an average piece of furniture, all with maximum comfort in a minimum of space.

The realization of this type of construction can encourage other companies to create eco minimalist architectural design, thereby seeking to reduce their environmental footprint and lead to rethinking mass residential building. The Applicant encourages other architects, designers, developers and contractors to develop and promote solutions to overconsumption. Oversized houses are outdated. By offering a unique usage scenario based on the sustainability objectives of eco-design, the system provides a long-term solution that follows us over time. Its raw materials and simple designs are timeless. The goal is to educate and inspire corporate actors to undertake such an approach in the context of a more conscious development of the environment for this growing sector of construction projects. Overall, the Applicant seeks to inspire a better management of resources among the population in the hope a healthier planet.
